Chemical Structure

Gossypetin-7-glucoside CAS 489-34-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 480.38 g/mol gives Gossypetin-7-glucoside distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Gossypetin-7-glucoside (CAS 489-34-9) is a high-purity analytical reference standard with the molecular formula C21H20O13 and a molecular weight of 480.38 g/mol.

The molecular framework of Gossypetin-7-glucoside (C21H20O13) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Gossypetin-7-glucoside meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
